Islam
Kalavun
Baibars' sons were unable to succeed their father. Instead, his great general, Kalavun, seized power in December 1279. Abaga tried to take advantage of the situation by raiding in force, capturing Aintab, Baghras and Aleppo. But Kalavun raised a large army and again the Mongols retreated in the face of the Mamluks. In September 1281, Abaga tried again, invading Syria with two full armies. One, commanded by the Ilkhan's brother, Mangu Timur, went by way of Aleppo to the Orontes River. Kalavun marched north and met Mangu Timur at Homs on October 30. He won, but was unable to follow up and was unable to advance against Abaga and the other army.
Abaga simply had too many men committed on other fronts to be able to invade effectively, or to risk pitched battle with the victors of Ain Jalut. The Euphrates River now became the more or less permanent frontier between the Mameluks and the Mongols.
The following year came news of the Sicilian Vespers. There was now no leader in the West who could pose a serious threat to Islam. The ten year truce of Baibars was ending. It was time to sweep the Christians into the sea.
That story, however, I tell elsewhere. Here I will turn to a short description of the Mamluks.
